To all whom at may concern Beit known that I, HENRY, A. Wren 7001);,

av citizen of the United States, residing at New York; inthe county of New York and of which the following is a specification.

This invention relates to the drying of stereotype matrices. 1 w a The principal objects of the invention are to provide for dryingsuch matrices-in a continuous uninterrupted operation by the employment; of exceedingly simple .mecha nism so as to make the operation short and exact, thereby. uniformly drying the matrices and saving much space and time in the operation; to provide anexceedingly simple means whereby the necessary pressure can be applied to the drying blankets in a uniform manner: throughout the drying operation, soarrang'ed preferably. that although the pressure is substantially uniform throughout the extent vof thematrix, it will very. gradually increase during the drying operation; and to provide means vwhereby the friction between theblankets and the be reduced so as to prevent the creeping of the blankets and matriX; w.

The invention also involves improvements in the manner of mounting the blankets on the form;

Further objects and advantages of the invention will. appear hereinafter.

used with the form of the machine shown in Figs. '9 and -10.-

Referring first to the first four figures, the

invention is shown as embodied in ajform in which thematrix heating'device proper comprises a stationary steamtable 10. This steam table has a plane surface on :the top on which the forms 11 are adapted to rest and along which they can bemoved by hand or power. 7 In the present instance each form is shown as having a pin 12 on each side and two endless chains 13 are provided having projections ltiat intervals for engaging thepins and moving the forms along the table. The .endless chains are shown as driven-by a motor 15,- shaft-16', worm *17, and worm-wheel 18 on a shaft .19 on'which two of the sprocket wheels 20 are located. The details of the driving mechanism are not. shown herein' Any :desired kind of mechanism can be employed for driving the chains eithercontinuously or intermittently, as desired.- Inthis form of the invention, the heating table is shown as provided with brackets '23 on which is located: a pressure shoe 24." Thisshoe preferablyzextends substantially throughout the width ofthe heating table and :over its entire length, except a' space'at one end on which the forms can be placed before they the shoe and a space attheother'end where the forms are left automatically by-the operation of the chains and from which they can be removedby hand or power, as desired. The shoe isshownas having beveled ends 25 for facilitating the entrance'and discharge-of the forms. Preferably it is finished on its lower side to'reduoe the friction so that the tendency of the blankets and matrix-.to creep "will be partly or wholly overcome. Y

Each of the forms is shown asprovided with apain of outwardly and downwardly extending-projections 28jat its forward end. The: drying blankets 29 which-rest on the matrix 30 are shown as doubled" or folded over a transverse rod 31 at the'front end of the-Eform; In Figs. 2 and 3 the blankets pass between the projections .28 and the rod'is, located up -under themso that when pulled Patented Jan. 9, 1917.

placed atfone the projection instead of passing between two of them. In this form the rod 31 is held up by' removable pins 33. InFig. 3 a smooth copper sheet 34; is employed over the be of any other smooth will not stretch, so as to prevent the creeping of the blankets and matrix and reduce the friction. This sheet is a movable member moving along at the same rate as the form. The space between the surface of the table and the adjacent finished surface of the shoe is a little less than type-high of the form, plus the height of the package of drying blankets sheet 34: when that is used. a

In the use of the device the forms are end of the table as they are received ready for drying. The blankets can be laid on the forms by hand before or after they are'placed on the table. The endless chainbeing started, the hooks 1 1 thereon will engage the pins 12. and move'the forms along under the shoe '24-. As the forms progress under the shoe, heated from below and themoi'sture is driven from the matrices into theblankets which are under pressure on account of the position ofthe' shoe 24. In this case the shoe is shown as slightly inclined from the receiv- It is to be observed that" the pressure exerted on the and the copper blankets .and matrix willbe substantially the parts 10, 12,

uniform throughout the heating operation in the forms shown in Figs. 5 and 9 but if the shoe is inclined, as shown Fig. 1, it will increase slightly but uniformly during theoperation- The chains leave the forms on the'other' end of the table from which they canbe removed at will. I I In the form s'hown in Figs. 5, 6, 7 and 8, 13, and'li are the same and i the chainsare operated in the same way. In

this case, however, a second pair of chains 45 35 areemployed driven in any desired way, and having thereon pressure plates 36.- The two chains are spaced and driven so that the pressure plates will be advanced with the forms as they are moved forward by the proj ections 14:. The blankets are attached to the pressure plates by means of clamps37 shown in Figs. 7 and ,8. These clamps are operated by means of aneccentr'ic shaft 38 and an operating arm 89' thereon. This shaft has holes 4 L for the reception of the end of a rod for turning the shaft. In this Case another modificationisshown in that the pressure is obtained bymeans of a fixed bar 40 having a spring-pressed shoe 41 p in contact with the pressure plates asithey are moved along. The compression ofthe springs 42 tends to. press the blankets into-the matrix.v The shoe-4:1 is held in place by headed studs 43 which connect it with the stationarybar 4:0 and prevent its fallthey are thoroughly In the form shown in Figs. 9, 10' and 11,

similar conditions prevail as in Fi 1, but in this case the creeping of the blanIrets and matrix is prevented and the friction reduced by the use of an endless belt 45 which runs between the fixed shoe 46 and the pressure plates 47 which are located above the matrices. These pressure plates are supported by springs 48 from plates 19 that rest directly on the blankets. They are held in position and their upward motion limited by headed studs 50. 1

It will be seen that in all the forms shown the matrices can be dried quickly and uniformly under either a perfectly uniform or uniformly increasing pressure the latter being shown in Fig. 1 and that the devices for reducing friction while not absolutely necessary add greatly to the efiiciency of the device.

While I have illustrated and described several forms in which the invention can be embodied, I am aware that the drawings do not exhaust all the ways in which the invention can be carried out and therefore, I do not wish to be limited to all the details of construction herein shown and described,

but
